Disabled celll number

So I had 24 months contract with vodacom and was due for an upgrade in September 2020.i went to the branch, only to be told that I was three months behind. I was surprised because my account was still active. Immediately my account was converted to prepaid. Three months down the line my number was inactive. I phoned customer care and was informed that I was handed over to RM lawyers and I will never use my number again as it was deleted from the network. Was not informed of anything. Now their so called legal department could be so rude it's unbelievable
